the line Y Y of Fig; 41.1 The type bar plate comprises a ring with typehars lmounted \concentrically thereonand '-pivote'd in the through .the central opening 4inthe ringlto a coininon' printing center onthe.- platen, S. The 'type' bar plate is .inclined slightly yhack- Ward from the perpendicular in order that the machine andthe printingcenter-niay be clearA and unobstructed.

By attaching the connecting wire 1S to t-he end 'of the rock shaft directly alzo-ve the line of vision and the connecting wire 20 to the other end of the rock shaft I remove the connectnig wii'e2() out of the line of vision hetween the operator' and the platenf.

In the type bai' plat-e I have arranged' type hars pivoted in two circles concentric with the printinfr point, the whole set iii lioth circles being a ined to strike at the common printing point.` One of the two circles is of smaller radius than thel other and hence the type hars pivoted therein are shorter than 'those in the other circle.

By this arrangement itwill he seen that longer pivots can he provided for the several type hars than would lie-possible in case all of the pivots were arranged in al sinelecircle; by this arrange-l inen'talso it follows that the type vheads when in then-normal posit-ions will rest not all in one circle, hutin two circles corresponding to the two circles of pivots. Lac-h ot the type-bars carries av'type head l5 with twol type characters, and part of the type hars have type heads wit-h three characters each. The type heads on the hars dirertly\ahove andl belowthe printingcenter are inline with ai'e placed on the bars at right angles'.

their bars. But as the bars are arranged on the sides of the ring as well-as ahove and hel other circle are liable to collide when being driven to the printing Vpoint or returning therefroin,' with the nextadjacent. type harI .whentlie latteiis moving in the opposite di rection. -In order to guard against this danger I have provided clearance vliends in the shanks oft-he type bars pivoted in the larger circle, for the type heads of the liars pivot-ed. in the smaller-'circle to lie in when at rest and to play through. when adjacent type hars are moved in quick succession t-o andV from the printing point. have their shanks extending in substantially radial lines excepting for the clearance liends in Athe liars pivoted in the larger circle, which latter liars have bends provided at 'just the points. needed. for clearance ot'. the heads on the lia-rs in the smaller circle.' i' The type heads which are set'obli iiely on their hars The type liars' as shown.

on Athe shuxiit liars fit nice v into lthe doulile hends on t'iie lonffheirs', because the end of the type head onne' side of the long bar is lower down on tlie'bary than is the one on the other side of tlie-long'har. y

Figs. 3 and. show the arrangement oi' the hars on one side ol" the pe har pla-te, extending from the bai-directly below the printing 'center around the side of the type liar plate and 'up to the. har directly ahove the printing center.

The paper carriage 4. is mount-ed at'its' rear edge oirtlie guide rail 3 andlis fastened to the railfhy grooves in the carriage and coi"- responding grooves in the guide rail, and hearing halls iii the grooves. The carriage is free to travel onthe'i'ail on the bearing halls.
